HPUX to Linux awk conversion
I have the following script to edit ^'s and newlines out of files to be entered into a database. This script has been around since the dawn of time (way before me).

Code:
#!/bin/bash

# Remove all ^ and \n from the source file, except do not remove ^^^\n
 cat myfile.hold  | awk '
 BEGIN {FS="|"; OFS="|"; OUTPUT=""}
 {
  gsub("\^$","",$0);
  gsub("\^\^$","^",$0);
  OUTPUT=OUTPUT $0;
  if (match(OUTPUT, "\^$"))
  {
   printf ("%s\n", OUTPUT);
   OUTPUT="";
  }
 } ' - > UNIQUENAME.out
 mv UNIQUENAME.out /testing/name.out

The probelm is when the script is moved from HPUX where it works great to Linux it gives the following error:

Code:
awk: cmd. line:4: warning: escape sequence `\^' treated as plain `^'

I dont know enough about awk and have attempted to research it and but i am having no luck.

Thanks,

Sean

ExtUtils::Typemaps::OutputMap(3pm)			 Perl Programmers Reference Guide			ExtUtils::Typemaps::OutputMap(3pm)

NAME

       ExtUtils::Typemaps::OutputMap - Entry in the OUTPUT section of a typemap

SYNOPSIS

	 use ExtUtils::Typemaps;
	 ...
	 my $output = $typemap->get_output_map('T_NV');
	 my $code = $output->code();
	 $output->code("...");

DESCRIPTION

       Refer to ExtUtils::Typemaps for details.

METHODS

   new
       Requires "xstype" and "code" parameters.

   code
       Returns or sets the OUTPUT mapping code for this entry.

   xstype
       Returns the name of the XS type of the OUTPUT map.

   cleaned_code
       Returns a cleaned-up copy of the code to which certain transformations have been applied to make it more ANSI compliant.

   targetable
       This is an obscure optimization that used to live in "ExtUtils::ParseXS" directly.

       In a nutshell, this will check whether the output code involves calling "set_iv", "set_uv", "set_nv", "set_pv" or "set_pvn" to set the
       special $arg placeholder to a new value AT THE END OF THE OUTPUT CODE. If that is the case, the code is eligible for using the
       "TARG"-related macros to optimize this.	Thus the name of the method: "targetable".

       If the optimization can not be applied, this returns undef.  If it can be applied, this method returns a hash reference containing the
       following information:

	 type:	    Any of the characters i, u, n, p
	 with_size: Bool indicating whether this is the sv_setpvn variant
	 what:	    The code that actually evaluates to the output scalar
	 what_size: If "with_size", this has the string length (as code,
		    not constant)
